1. Why is it better to have only 2 choices at each step instead of more?
It's easier to compare if there is only two choices.
2. What problems did you encounter in using the dichotomous key? Be specific and discuss fully.
We had trouble with the Jaw Breaker and the Fireballs.
3. How did you resolve your problems in #2?- We used the name that sounded more like the candy.
4. Do classification keys go from general to specific characteristics or from specific to general characteristics? Explain why.
It goes from general to specific characteristics, because we found what the scientific name for the candy by naming the the general characteristics.
5. What does the first and second part of the Latin name represent in the scientific name of the organism?- A formal system of naming species is called binomial nomenclature, binomial nomenclature, or binary nomenclature.
6. Research Carolus Linnaeus and his contribution to modern classification- He was a botanist. he started to classify plants and putting them in a specific group.
.
7. What is a dichotomous key? (define)- Means "divided into two parts" a tool that allows the user to determine the identity of the items.
8. What is binomial nomenclature? (define)-System of nomenclature in which two terms are used to denote a species of living organism.
10. List the order of classification groups from Kingdom down to species.

Exercise
Procedure: Our exercise was jumping jacks. Alexis did them for ten minutes. We stopped her within five minutes then we took her blood pressure, heart rate, and perspiration. She did the jumping jacks in the hallway outside the classroom. Amber was timing her and Marrissa kept track of the vitals while she did her jumping jacks

Analysis:
1. What are the changes that you observed throughout the experiment? She started sweating, skin turned pink
2. How do each of those changes help the body adjust to maintain equilibrium (homeostasis)? Sweating means that her body is warmed up.
3. What mechanisms are used to maintain body temperature in the body? The sweat cool your body down.
4. What is the purpose for an increased respiratory rate and heart rate?The heart started to beat faster for more blood to pump through.
5. Write a paragraph about the conclusions you can draw about your body's ability to maintain equilibrium (homeostasis.) Be sure to discuss some of the information from your other answers.
Your body's ability to maintain homeostasis consist of sweating, and difference in heart rate. One reason why sweating helps your body's ability to maintain homeostasis is because when you start to exercise your body warms up and you start to sweat. As you sweat it cool off and cools your body temperature. The heart rate also helps your body to maintain homeostasis because when your exercising your heart needs more blood to through it to try to keep it going as if you weren't exercising. That is why your heart rate increases.
Protists
Daphnia
Heterotroph Where Found: They can be found in acidic swamps to fresh water lakes, ponds, steams, and rivers. FACTS:
People call it the water flea, the scientific name for Daphnia is cladocera, and there breeding process is really good.
It can grow to between 0.2 to 5 mm long.
The lifespan for Daphnia does not exceed to one year and are very temperature dependent. http://en.wikipedia.org/wiki/Daphnia
Green Hydra
Heterotroph Where Found: They can be found in shallow water. FACTS:
They are related to jelly fish.
It can grow up to 30 millimeters long.
They don't like to float.
They reproduce by budding- the grow bumps on their body. When it grows tentacles it pinches itself away from the parent. http://www.fcps.edu/islandcreekes/ecology/green_hydra.htm
Brown Hydra
Heterotroph Where Found: It is an easy organism to be found in still waters from Spring to late Autumn. FACTS:
When disturbed it retracts into a small brown blob, which is usually over looked.
When in feeding mode it's tentacles extend to about an inch long.
They are commonly found attached to the stems of water plants. http://en.wikipedia.org/wiki/Hydra_oligactis
